Abstract
Method for isotopic identification, allowing, where appropriate, a liquid to be linked to a site of growth or harvest or a sub-product derived from a determined liquid, via analysis of concentration or of ratios of stable isotopes, and comparison to isotopic codes generated beforehand in a manner unique to a set of liquids issued from a site of growth, harvest or conversion. The invention also relates to a method that makes it possible to give a unique code to liquids of a site of growth, harvest or conversion, and to a computer making it possible to store the unique codes generated in memory, to generate unique codes for new liquids of a site of growth, harvest or conversion and to perform comparisons.
Claims24
A method allowing a specific code of a place of origin to be applied to liquids, preferably wines or spirits, or to by-products of this liquid;
- method wherein the basic geographic signature (BGS) is provided of the liquid or by-product thereof, comprising:
- (i) the concentrations of at least 5, 6, 7, 8, 9, 10, 11, 12 or the entirety of the elements in group (3):
- Rb, Sr, B Li, Ca, Na, Mg, K, F, P, C1, As, Pb, Cd,
- (ii) the concentrations of at least 5, 10, 15, 20, 25, 30, or the entirety of the elements in group (2):
- Be, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Se, Y, Zr, Nb, Mo, Rh, Pd, Ag, Sn, Sb, Te, I, Ba, Hf, Ta, W, Re, Ir, Hg, Ti, Si, and
- (iii) the concentrations of stable isotopes stables of at least 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 of the elements in this group (2);
- the method comprising the addition to this liquid having this BGS of a known quantity of at least 1 stable isotope of at least 1, 2 or 3 chemical elements of group (2), by means of which a liquid is obtained having a determined isotopic signature, with a modified isotope ratio compared with the BGS.
An isotopic identification method allowing a liquid or by-product, preferably a wine or spirit, to be linked with a place of origin, the method comprising:
- a—in a sample of liquid or by-product, measuring:
- (i) the concentrations of at least 5, 6, 7, 8, 9, 10, 11, 12 or the entirety of the elements in group (3) Rb, Sr, B Li, Ca, Na, Mg, K, F, P, Cl, As, Pb, Cd,
- (ii) the concentrations of at least 5, 10, 15, 20, 25, 30, or the entirety of the elements in group (2):
- Be, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Se, Y, Zr, Nb, Mo, Rh, Pd, Ag, Sn, Sb, Te, I, Ba, Hf, Ta, W, Re, Ir, Hg, Ti, Si, and
- (iii) the concentrations of stable isotopes of at least 2, 3, 4, 5, 6, 7, 8, 9 or 10 of the elements in this group (2);
- to obtain a profile of concentrations of elements and stable isotopes;
- b—comparing this profile with profiles recorded in a predefined model (M) having profiles in memory in the form of unique codes each specific to a type of liquid or by-product from a place of origin, each unique code having been previously generated by the model (M) with a variation in isotopes of elements;
- c—concluding that the liquid or derivative by-product to be identified has a profile substantially equal to a recorded code and hence indicating a place of origin, if after comparison the profile corresponds to a recorded profile, and on the contrary concluding that the liquid or derivative by-product does not come from any place of origin having a code recorded in the model, or that the liquid has been adulterated.
